I use a PD9160 with the charge wizard pedant, I don't think you can go wrong with the PD series as long as you have the pendant.
So far I have been able to get 9yrs of use from a pair of 6V GC2s combined with my PD9160 with charge wizard. Would consider another PD series if my current one quits.
With that said, Iotas, as long as you have the IQ4 pendant seem to have similar specs to the PDs. Don't think I have heard anything bad posted about Iotas with IQ4 pendant.
If you didn't mind upgrading your wiring, there is a surplus electrics outlet which currently has Iota DLS-90 units for $125, they are working "pulls" from some sort of equipment so they are selling as used.
Find that
HERE, the IQ4 pendant is not included with that unit but the price is right for 90A..
